* fix(native-chat): keep a huge unbroken paste from freezing the chat
A long run with no whitespace ("xxxx…", "0000…", "abab…") wrapped with
kerning makes Chromium reshape it at every line, quadratic in run length:
128 KiB stalls 2.4 s, 1 MiB 19 s, 5 MiB never finishes. ProseMirror forces
that layout on paste and on each keystroke, so the composer freezes in
every terminal-backed chat, including paired servers and WSL. A sent
message stalls the transcript the same way: its fold clips the text but
still lays it all out (128 KiB: 2.5 s).
Runs over 256 characters now render with font-kerning: none, so prose of
any length and Shift+Enter lines keep kerning:
- composer: inline decorations, updated only for the lines a transaction
touches (a keystroke beside 8,000 decorated lines ~1 ms, not ~190 ms)
- user messages in the transcript and expanded queued cards: the whole
text when it holds such a run
Text, drafts and what is sent are unchanged. After: 1 MiB single line
84 ms, 5 MiB 312 ms (keystroke 248 ms), 1 MiB of 4000-char lines 50 ms
(was 2.3 s), transcript 128 KiB 80 ms. Worst case left kerned, 256-char
runs: 1 MiB 242 ms, 5 MiB 1.2 s, like 1 MiB of short lines (291 ms).
Fixes #32355

* fix(native-chat): keep kerning on long CJK and Thai paragraphs
These scripts have no spaces but Chromium can break between their
characters, so a long paragraph is not one unbreakable run. Count
ideographs, kana, Hangul and Thai as break opportunities so such text
keeps kerning.

* fix(native-chat): rescan only the edited run, and wait out IME compositions
Splitting one run inside a block of thousands replaced every decoration
in that block, and ProseMirror's removal is quadratic: 1,411 ms for one
space in a paragraph of 8,000 long runs. A change now rescans only from
the run edge before it to the run edge after it, and removes only the
decorations that overlap: ~1 ms for the same edit.
Decorations are only mapped while an IME composition is in progress, so
the composing text node is not re-rendered. The deferred range is
rescanned with the next non-composing change, or on compositionend when
none follows.
The keystroke-timing test is replaced by deterministic ones: unaffected
decorations are reused and the result equals a full scan; a composition
defers the rescan and compositionend runs it.

* fix(native-chat): never split a CJK code point, and treat NBSP as glue
A supplementary ideograph (U+20000-U+3FFFF) broke a run at its high
surrogate only, so the decoration began on the low surrogate and split
the pair across elements. Both the run scan and the leftward edge scan
now treat the pair as one break.
NBSP joins words for Chromium's line breaker (UAX #14 class GL), so an
NBSP-joined paste is one unbreakable run and must lose kerning; drop it
from the break set. No other non-breaking characters were in it.
Drop a composer test whose coverage the decoration reuse test already
has.

* fix(native-chat): classify surrogate pairs whole at a rescan's edge
Two lone-surrogate edge cases made the incremental rescan disagree with
a full scan:
- an edit completing a pair at the window start (a lone high surrogate,
then a pasted low surrogate and run) began the decoration on the low
surrogate; the window now widens past the whole pair
- a lone low surrogate after any break counted as a pair end, dropping
it from the run; that now requires a preceding high surrogate
A seeded fuzz also found inclusive decoration edges mapping across a
joined block's boundary, where ProseMirror cannot remove them; the
decorations are no longer inclusive.
